Advanced level STEM kits. All the engineering, diploma and other technical students from first year to final year can get hands on experience in designing and developing various electronics projects. Self-explanatory, fully supported by elaborate documentation to independently complete the project work.

All the engineering, diploma and other technical students from first year to final year can get hands on experience in designing and developing various electronics projects with these real-time solder less project kits. Complete assembled project is available in image format besides real time working in audio visuals to help students to complete the experiment with ease and then try engineering skills to attempt the other free circuits.

Foot Step Activated Door Bell:

Door bells are used in houses in order to alert the household in the event of persons to visit their house.

This System is cleverly built and intelligently alerts the household about any person who knocks his/her main door of their house. In the event of Knocking, the piezo sensor which is attached with the door picks up the sound and converts that to an electrical signal which in turn activates a 555 timer running in monostable mode, This 555 timer in turn activates a Melody generator IC through which a speaker of 8 ohm 0.5 watt is driven delivering a melodious music, hence alerting the household about the outside person is waiting at the door. The time for which the melody sound to be activated can be set using an adjustable RC time constant, thus making user friendly and hence a smart way of using the technology at homes.

Further this system can be enhanced with some advanced sensing features like ultrasonic sensor which activates an alarm in the event of Intruder trespassing the compounds.
